Pat 3 pounds chuck roast dry and season it with 2 teaspoons salt, 2 teaspoons pepper, 1 teaspoon dried oregano, and ½ teaspoon garlic powder.
Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Once hot, add the seasoned chuck roast and sear it for 2 to 3 minutes per side until browned. Remove the roast from the skillet and place it in a slow cooker.
Add 1 small yellow onion, diced, to the skillet and sauté for 5 to 7 minutes until softened. Transfer the onion to the slow cooker with the roast.
Pour 1 can French onion soup and 1 cup beef broth over the roast and onions in the slow cooker.
Cover and cook on low for 8-10 hours until the roast is fork tender.
Remove the roast from the crock pot and shred it with 2 forks.
Mix 2 tablespoons cornstarch with 2 tablespoons cold water, then stir the mixture into the juices in the crock pot. Cover and cook on high until the juices begin to thicken.
Add the shredded beef back to the crock pot and stir it into the sauce to coat it with the sauce in the crock pot.
Serve warm with your favorite sides and enjoy!
Notes
You can cook this recipe on high in the crock pot but we prefer it on low as the beef is more tender! You can use an arm roast instead of chuck roast in this recipe if you prefer.Refrigerate the leftovers in an airtight container for up to 5 days.
